The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 1800 UTC surface analysis and satellite imagery through 2255 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic through the coast of Sierra Leone near 07N12W and continues to 03N21W. The ITCZ extends from 03N21W to 02S30W to 01S42W. Scattered moderate to isolated strong convection is observed within 120 nm of the monsoon trough and ITCZ. The strongest storms are occurring E of 20W. ...GULF OF MEXICO... The cold front that moved across the Gulf of Mexico during the past few days now stretches from the western Atlantic to the NW Caribbean Sea. A high pressure system over the southern United States extends into the gulf, resulting in fairly tranquil weather conditions. Fresh to strong anticyclonic winds are found E of 94W, with the strongest winds occurring in the E Bay of Campeche and within 60 nm of the coast from SE Louisiana to the Florida panhandle. Seas in the region described are 6-10 ft S of 25N and 6-8 ft N of 25N. The highest seas are occurring in the E Bay of Campeche. Elsewhere, gentle to moderate winds and 3-6 ft seas prevail. For the forecast, high pressure is building across the area in the wake of the recent cold front. Fresh to strong north to northeast winds south of 26N will diminish tonight. Fresh to strong west north winds over the northern Gulf east of 94W are following in behind a secondary cold front. This front will quickly move across the NE Gulf this evening. These winds will continue through Sat while shifting to the NE Gulf. Fresh to strong east to southeast return flow is expected in the western Gulf on Sat night and through early Wed afternoon. ...CARIBBEAN SEA... A cold front extends from western Cuba to southern Belize in the NW Caribbean Sea. A few showers are noted near the frontal boundary. The rest of the basin is dominated by the sprawling 1025 mb subtropical ridge positioned near the Azores. Fresh to strong N-NE winds are present at the entrance of the Yucatan Channel with seas of 4-7 ft. Similar wind speeds but easterly are observed in the south-central Caribbean Sea, with the strongest winds occurring off the Colombian coast and in the Gulf of Venezuela. Seas in this area are 5-7 ft. Elsewhere, moderate to locally fresh trades are present in the north-central and eastern Caribbean, while light to gentle winds prevail in the NW Caribbean ahead of the front. Seas are 2-5 ft. For the forecast, fresh to strong northeast to east trade winds will pulse late at night in the south-central Caribbean near the coast of Colombia tonight and Sat night and remain steady afterwards through Wed night. A late-season cold front extending from west-central Cuba to the Gulf of Honduras will move across the rest of the northwestern Caribbean through Sat while weakening. Fresh to strong north to northeast winds behind the front will cover the western Caribbean on Sat. The front will dissipate by Sun allowing for winds to diminish to moderate to fresh speeds. High pressure building in behind the front will increase northeast to east winds across the northwestern and central Caribbean from Sun night through at least Tue night. ...ATLANTIC OCEAN... A cold front extends from 31N73W to western Cuba and some cloudiness and isolated showers are observed ahead of the frontal boundary. Fresh to strong SW winds are found ahead of the front, mainly N of 28N and W of 68W, with seas of 6-9 ft. Behind the front, moderate to locally fresh W winds and seas of 3-6 ft prevail. Moderate to locally fresh SE winds are affecting the waters S of 23N and between 60W and the eastern Bahamas. Seas are 4-6 ft. The rest of the Atlantic is dominated by a high pressure of 1025 mb positioned near the Azores that maintains fairly tranquil weather conditions. A cold front is located north of our area in the central Atlantic and the pressure gradient between the front and the high pressure result in fresh SW winds N of 29N and between 33W and 45W. Seas in this area are 6-8 ft. Moderate to locally fresh trades are noted S of 20N between Africa and the Lesser Antilles. Seas in the area described are 6-8 ft. Fresh to strong NE winds are present N of 20N and E of 18W, with the strongest winds occurring off Morocco. Seas are 4-7 ft. Elsewhere moderate or weaker winds and 4-7 ft seas prevail. For the forecast, the aforementioned front will reach from near 31N72W to the central Bahamas and to eastern Cuba Sat morning, and from 31N64W to the Windward Passage by Sun morning. The front will become stationary and weaken over the southeastern part of the area late Mon through Tue. Strong west to northwest winds are expected behind this front through Sun. A second cold front will push off the Florida coast early Sat. This front will bring widespread strong to near gale-force winds and building seas on Sat and Sun. High pressure will build over the area early next week which will improve conditions over most of the forecast waters. This high pressure will lead to increasing northeast to east winds near the Windward Passage from Mon night through Wed night. $$ DELGADO
